Uni Ecto Plugin

Let's assume you are using the popular triplex library (which implements the uni pattern) or the unifex approach. For this guide, we will use a generic setup based on the uni_ecto_plugin pattern.

defmodule MyApp.Blog.Post do
  use Ecto.Schema
  use UniEctoPlugin.SoftDelete   # adds deleted_at, soft_delete/2, restore/2
schema "posts" do
field :title, :string
field :body, :string
timestamps()
end uni ecto plugin
def changeset(post, attrs) do
post
|> Ecto.Changeset.cast(attrs, [:title, :body])
|> Ecto.Changeset.validate_required([:title])
end
end
 Let's assume you are using the popular triplex
